Grafting device

The invention discloses a grafting device which comprises a first working arm and a second working arm. The second working arm is hinged to the first working arm. The front end of the first working arm is provided with a notch for a branch to be cut to extend into, an M-shaped grafting knife used for cutting the branch to be cut is movably arranged on one side of the notch, the other side of the notch is matched with the M-shaped grafting knife to clamp a cushion table for the branch to be cut, and the second working arm is in movable contact with the M-shaped grafting knife. The M-shaped grafting knife is clamped with or separated from the cushion table along with the rotation of the second working arm. By using the M-shaped grafting knife of the grafting device, the grafting contact surface is greatly increased, and the grafting seedling rate is remarkably increased. Meanwhile, a guide column is matched with an arc-shaped guide groove and a linear guide groove, so that high graftingefficiency is achieved, a
